Typedefs
using	Ice::bad_optional_access = std::experimental::Ice::bad_optional_access
	Raised when accessing an optional that doesn't contain a value. More...
using	Ice::in_place_t = std::experimental::Ice::in_place_t
	This type indicates that an optional value should be constructed in place. More...
using	Ice::nullopt_t = std::experimental::Ice::nullopt_t
	This type indicates that no value is provided. More...
template<class T >
using	Ice::optional = std::experimental::Ice::optional< T >
	Ice::optional is a placeholder for std::optional. More...
